My Beautiful Disciples, I'm really not the Main Character!

"I got transmigrated into a novel because of a bad review?"





Eren found his life turned upside down when he woke up as the character that he had just finished cursing in a negative review!





Not only had he been reborn as an antagonist that he hated, but he was an Elder at a Devilish Sect?





It would've been fine if that was the only problem, but that was just the beginning as he remembered that the Character was a spy sent into the Devil Sect by the Mythical Hero Academy... A character that died within the first fifty chapters?!
